It looked like that Infiray is rebranded as Raythink Technology. I got an email from the same guy who responded to my questions regarding the Infiray M600 firmware now asking if I wanted to partner up with them.
I hope he's doing alright. Infiray.com is definitely missing a bunch of cameras including the M300 and M600 series. Glad I downloaded everything I could for these.
Edit: Spoke a bit too soon. Raythink might be something else entirely?
